IPC: H01R13/639
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To waterproof a lock mechanism and moreover allow the lock mechanism to generate loud sound in regular fitting. SOLUTION: For a through-hole 22 that is provided with a lock arm 23 in a penetrating form and sealed with a waterproof seal 24, almost its lower half part is extended to the back side of a back wall 12 so as to form an extended part 34 and a pair of sounding plates 35 are protrusively formed opposite to each other. The sounding plates 35 are so placed as to come into contact with the upper surface of a contact part 36 of the rock arm 23 which is not in a slantwise movement state. When both connectors 10, 40 are being fitted to each other, the back end side of the lock arm 23 is lowered in the course of the fitting, so that the contact part 36 is separated below the sounding plates 35. When both the connectors 10, 40 are fitted to each other regularly, while the lock arm 23 is brought into restoring deformation, its front end side is locked.  At the same time, the rear end side of the lock arm 23 is energetically deformed upwards, hence a loud sound is generated by hitting the contact part 36 against the sounding plates 35.
